Usage
=====
Adopt is a simple library for parsing UNIX-style command line arguments in
Common Lisp. It was made because none of the other libraries did what I needed.
[TOC]
Package
-------
All core Adopt functions and macros are in the `adopt` package. You can `:use`
that if you really want to, but it's probably clearer to use namespaced
`adopt:…` symbols.
Interfaces
----------
define-interface and usage. nothing else.
Parsing
-------
`parse-options` with a bare-bones interface.
Options
-------
talk about the option arguments.
Short and Long Options
----------------------
short versus long arguments. 1+ is required.
Initial Value
-------------
at this point it's just a default
Reduce
------
talk about reducers. mention argparse's:
`store_const` is `(constantly x)`
`store` is `#'latest`
`store_true` is `(constantly t)`
`store_false` is `(constantly nil)`
`append` is `append1`
`append_const` is `(rcurry #'append1 x)`
`count` is `1+` with an `initial-value` of `0`.
need to figure out `help` and `version`.
Usage Printing
--------------
It's `(print-usage interface)`.
